What I have is; 72.00 trans 60 caps 35 choke 18connectors(RCA's IEC etc.) The Chassis was free from old parts passive parts 35 donated mos-fets Looking at about 250$ all told. Considering the level of quality and design about 1/10 the price you would pay retail. The custom chassis I intended to use is 220$ but nice; so you could go close to 500$ with very high quality chassis.
